Just saw this on Twitter.

That's the palace itself. I've yet to find any news stories about it, and the only links to the video are all coming from Twitter... so yea. But pretty unbelievable what they did and then the guy posting the video (click through to go to YouTube) is the one that did it. They spray his YouTube user name on the walls there - ballsy, certainly, but this whole thing is juvenile.
Ya... just wanted to post it. Watch it through to the end.
